You can refer to this support doc for more information on size limits. We understand this technical limitation is far from ideal and are looking for ways in which we can increase the file limit but nothing we can commit to announcing at this moment. I'd say that your solution to this restriction should work as long as the limits are not reached, but I also understand the extra hassle. If you feel comfortable answering how many 4GB or over you currently have, it could give us a pulse on this particular user pain point.
